"Yes, we can only observe him here. Liu Yang, could you please inform his family about what to pay attention to during the observation?"
Now that Liu Zheng had decided to admit this person to the hospital and take care of the arrangements himself, he had to thoroughly test this kid to see if he truly knew his stuff.
"You have to do this: every so often, you need to gently tap the child to see if he falls into an unconscious state or if he is in a coma. If that happens, you must quickly call for a doctor because we need to treat him urgently."
"But, what about sleeping at night? We can't let him sleep, can we?"
"Tonight is a special night, so even if he does sleep, you still need to do this—about every 40 minutes to an hour, you'll need to shake the child. Then, as long as he opens his eyes and can respond to you, everything is safe. If it's still like this tomorrow morning, then we can basically determine that he is likely out of danger."
"Okay, I understand."
